You Want To Know WHAT?!

Why would a rabbi ask a potential convert to list all the medications that she may be taking?

The rabbi who has agreed to help me learn towards my conversion has given me an application to fill out. It asks the usual "why do you want to convert?" - type questions, but also contains a rather detailed section on personal medical information, including medications an applicant might be taking and why, family medical history, date of last complete physical, etc.

While I understand it is important to verify that I am not an axe-wielding maniac and that my intentions are true and good, I fail to understand why my rabbi needs to know the date of my last pap smear or what brand of birth control pill I may or may not be taking.
